NSWA
This addon collection solves some problems I've had with the WoW UI:
- hide talking head
- hide error messages
- temporarily display which M+ dungeon I joined
- alert me, when the group is considered full
- alert group when the dungeon difficulty is not set to mythic
It's entirely tailored to my needs, so it might not suit your needs. But you're welcome to use this code however you like.
Note: You call this addon ingame via /nswa or /wa. The latter will
conflict with Weakauras.
